NOTICE
A poorly maintained battery will quickly
deteriorate.
1. Check the electrolyte level.
2. Check the battery's charge. If your boat
is equipped with the digital speedome-
ter, the voltmeter and low battery alert
functions will help you monitor the bat-
tery's charge. If the battery needs charg-
ing, consult your Yamaha dealer.
3. Check the battery connections. They
should be clean, secure, and covered by
an insulating cover. WARNING! Bad
connections can produce shorting or
arcing and cause an explosion.
